The weight of a 4x12x20 rough sawed cedar beam can be estimated by using the density of cedar, which is approximately 25-35 pounds per cubic foot. A 4x12x20 beam has a volume of 9.33 cubic feet (4/12 * 12/12 * 20). Therefore, the weight of the beam would be roughly between 233 to 327 pounds, depending on the specific density of the cedar used.
